I can reproduce it too,

First snapshot works, but second snapshot hang, crash the qemu process

Maybe it's a bug in internal-snapshot-async.patch.

Creating one snapshots with RAM works, just try to create a second one with RAM after a few seconds fails with: 
Formatting '/var/lib/vz/images/100/vm-100-state-ram5.raw', fmt=raw size=4819255296 
TASK ERROR: VM 100 qmp command 'savevm-start' failed - client closed connection 

And the VM is stopped. I see this with local qcow2 storage, but also on ceph. 

Second issue: 
Creating a snapshot on NFS (qcow2 on NFS) seems to hangs forever with the snapstate "prepare" and the task log shows "Formatting '/mnt/pve/store-nfs /images/119/vm-119-state-ram1.raw', fmt=raw size=2671771648"
